On Sept. 5, 2021, for the first time, a large high-temperature superconducting electromagnet was ramped up to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created on Earth. That successful demonstration helps resolve the greatest uncertainty in the quest to build the world’s first fusion power plant that can produce more power than it consumes, according to the project’s leaders at MIT and startup company Commonwealth Fusion Systems.
It’s been hailed as fuel of the future. Hydrogen is clean, flexible and energy efficient. But in practice there are huge hurdles to overcome before widespread adoption can be achieved.
Video timeline: 00:00 How hydrogen fuel is generated. 02:04 How hydrogen fuel could be used. 02:46 Why hydrogen fuel hasn’t taken off in the past. 03:40 Is hydrogen fuel safe? 04:31 Hydrogen’s advantage over batteries. 05:00 How sustainable is hydrogen fuel? 06:13 Why the hype about hydrogen may be different this time.
The energy islands and the wind farms with a combined capacity of 5 GW are expected to be commissioned by 2030.
The North Sea energy island will have an initial capacity of 3 GW which could potentially be further scaled up to 10 GW offshore wind. This will be an artificial island.
Bioo is generating electricity from the organic matter in soil and creating biological batteries to power agricultural sensors, a growing $1.36 billion global market. Eventually, Bioo envisions a future where biology could help to power our largest cities.
Someone came up with the idea to build the world’s largest solar array in the Australian outback and then connect it to Singapore with a 3,750-kilometre undersea cable. This is how it’ll be done.
The Eiffel Tower was lit up with hydrogen-generated electricity for the first time.
A cyberattack on the U.S.’s largest fuel pipeline on May 7 forced a shutdown that triggered a spike in gas prices and shortages in parts of the Southeast. WSJ explains just how vulnerable the nation’s critical energy infrastructure is to attack. Photo illustration: Liz Ornitz/WSJ
There’s a lot of interest in the hydrogen fuel economy. Here’s what you need to know about how it works and the hurdles it faces.
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications. It can be used in cars, in houses, for portable power, and in many more applications.
Miles below the Earth’s surface, there’s enough thermal energy to power all of humanity for the foreseeable future. It’s called geothermal energy, and it’s poised to play an increasingly large role as a source of always available, renewable power. Now, there are a number of startups in the geothermal space, working to figure out how to access this heat in difficult to reach geographies, at a price point that makes sense. And it’s even gotten the attention of oil and gas industry giants, who are interested in greening their portfolios while sticking to their core competencies – extracting energy resources from deep within the Earth.
Retail energy companies compete with local utilities to give U.S. consumers more choice. But in nearly every state where they operate, retailers have charged more than regulated incumbents, meaning you may be paying more for your electricity than your neighbors. Here’s why.
